Jamie and Zoe play in the sand and water. The Doctor decides to get an ice cream. On the way, he encounters the boy, and they talk. The boy is not interested in the moon landing. The Doctor thinks the boy should tell his parents where he is, and the boy heads for home. Suddenly he is hit by a car, and the Doctor sees that his legs are broken beyond repair.

The Doctor runs back to the TARDIS, shouting for Jamie and Zoe to come along. Zoe can tell something is terribly wrong.

The Doctor tells Jamie and Zoe what happened, and they spend several months trying to get back to the Isle of Wight in time for the Doctor to prevent the disaster. They finally make it back to four hours before the car accident. The Doctor very carefully makes sure not to do anything he did before, especially not going for ice cream. The three watch as the boy and his family head for the beach for a barbecue. Once the time of the accident has passed, they leave in the TARDIS.

The Doctor goes back one more time, to check on the boy as he takes his bath. The boy is reassured by the sound of the Doctor's voice.
